摘要： A system, method and program product for blocking unwanted e-mails. An e-mail is identified as unwanted. A source IP address of the unwanted e-mail is determined. Other source IP addresses owned or registered by an owner or registrant of the source IP address of the unwanted e-mail are determined. Subsequent e-mails from the source IP address and the other IP addresses are blocked. This will thwart a spammer who shifts to a new source IP address when its spam is blocked from one source IP address.

摘要： Managing e-mails from a source suspected of sending spam. The e-mails are received at a firewall or router en route to a mail server. A determination is made whether a source has sent an e-mail which exhibits characteristics of spam. In response, subsequent e-mails from the source destined for the mail server are rate-limiting at the firewall or router such that the firewall or router limits a rate at which the subsequent e-mails are forwarded from the firewall or router to the mail server. The rate limit can be a limit on a number of e-mails per unit of time from the source that will be forwarded from the firewall or router to the mail server.

In response, subsequent e-mails from the source destined for the mail server are rate-limiting at the firewall or router such that the firewall or router limits a rate at which the subsequent e-mails are forwarded from the firewall or router to the mail server. The rate is predetermined and less than a maximum rate at which the firewall or router can physically forward e-mails to the mail server absent the rate limit. A determination is made whether another source has sent another e-mail which exhibits more characteristics of spam than the first said e-mail. In response, subsequent e-mails from this other source are blocked at the firewall or router. The rate limit can be a limit on a number of e-mails per unit of time from the source that will be forwarded from the firewall or router to the mail server.

摘要： A method of blocking spam at a firewall involves applying blocking measures for an adaptively determined duration. The blocking measure is then suspended while determining whether the spam has ended. If so, the method resets to an initial state. Otherwise, the blocking measure is re-applied for a second duration.
摘要翻译： 在防火墙中阻止垃圾邮件的方法包括对自适应确定的持续时间应用阻塞措施。 然后在确定垃圾邮件是否已结束的同时暂停屏蔽措施。 如果是这样，该方法将重置为初始状态。 否则，阻塞措施将重新应用第二个持续时间。

摘要： A method of, system for, and product for managing a denial of service attack in a multiprocessor environment comprising. The first step is establishing normal traffic usage baselines in the multiprocessor environment. Once the baseline is established the next step is monitoring outgoing traffic to detect a high proportion of packets being sent to a specific destination address, and a high number of outbound packets compared to said baseline. Next is monitoring ports and protocols to detect a high proportion of packets sent to a specific port, and a consistent use of a protocol for all packets for that port. If there is such consistent use of a protocol for all packets for that port as to evidence a denial of service attack, blocking measures are started to mitigate the apparent denial of service attack.

摘要： A detection and response system including a set of algorithms for detecting within a stream of normal computer traffic a subset of (should focus on network traffic eliciting a response) TCP or UDP packets with one IP Source Address (SA) value, one or a few Destination Address (DA) values, and a number exceeding a threshold of distinct Destination Port (DP) values. A lookup mechanism such as a Direct Table and Patricia search tree record and trace sets of packets with one SA and one DA as well as the set of DP values observed for the given SA, DA combination. The detection and response system reports the existence of such a subset and the header values including SA, DA, and multiple DPs of the subset. The detection and response system also includes various administrative responses to reports.

There is efficient use of a lookup mechanism such as a Direct Table and Patricia search tree to record sets of packets with one SA and one DP as well as the set of DA values observed for the given SA, DP combination. The existence of such a subset and the header values including SA, DP, and multiple DAs of the subset are reported to a network administrator. In addition, various administrative responses to reports are provided.

摘要： A method, apparatus, and computer instructions for providing a current and complete security compliance view of an enterprise system. The present invention provides the ability to gain a real-time security posture and security compliance view of an enterprise and to assess the risk impact of known threats and attacks to continued business operations at various levels is provided. Responsive to a change to an enterprise environment, a request, or an external threat, an administrator loads or updates at least one of a Critical Application Operations database, a Historical database, an Access Control database, a Connectivity database, and a Threat database. Based on a comparison of information in the databases against similar security data elements from company or external policies, the administrator may generate a Security Compliance view of the enterprise. A Security Posture view may also be generated by comparing the Security Compliance view against data in the Threat database.
